Fingerprints or dirt on disc surfaces can weaken the 

light reflected from the disc and directly influence the 
signal quality. The poorer the signal quality, the 
poorer the playback performance.  Keep the disc 
clean by wiping it straight out from the centre with a 
dry soft cloth.

If the disc is very dirty, wipe with a moist soft cloth, 

then follow with a dry soft cloth. 

?

 

Do not use record cleaning sprays, benzene, 

thinner, anti-static electricity liquids, or any other 
solvent. These may damage the disc surface.

Please keep the discs in their original cases to avoid 

bending  the discs. Do not keep discs in locations 
with high temperature, high humidity, or direct

damage to the discs.
